Examining Nutrition, Exercise, and Renewal Goals for Yourself

“Another practice for the development of attention is single-pointed concentration. Here the observer may choose any kind of object, external or internal, something that s/he can easily conjure the image of. The training proceeds with the deliberate placement of one’s attention on the chosen object and the attempt to hold that attention as long as possible.
This practice involves primarily the use of two faculties: mindfulness, which keeps the mind tied to the object, and introspective vigilance, which discerns whether distraction occurs in the mind and whether the vividness of the mind’s focus has become lax.
At the heart of this practice lies the development of two qualities of the disciplined mind – the stability of prolonged attention and the clarity or vividness with which the mind can perceive the object.”
the Dalai Lama
